My friend has just bought a kfx400 and it has like 5hrs on it and the axle got bent real quick and he didnt even hit any jumps. Also the bike is hard to shift into first from neutral on occasion and you have to double clutch it in order for it to go in to gear . the dealer wont cover the axle and they cant gget the tranny to act up. they thought it may be the reverse cable to tight.
